Chapter -13 (Macros in Detail)

Macros(Pre-processor Directive):-

These statements are declared with #define statements. All the simple statements will occupy space in main memory, but macros will occupy space in buffered memory, so their execution speed is much better than other statements. They will also shift themselves to the desired statement when we use them.

Example:-

#define  add +

int a=10,b=20,c;

c=a add b;
